Maybe it was just me. I got this distancing thing from Steve at teh jail when he talks to Danny. And then in the car, Steve's trying to reach out and Danny's kinda poopooing him off, and the "Don't give me that look. That face" like he was expecting Steve to say I told you so...

And then the team rallying at the end for beers and Danny's off by himself in his office...

Again these are just my observations, but I agree with you, D is trying to convince himself he's fine when he ain't.
